Earth’s climate is warming as a result of anthropogenic emissions of greenhouse gases, particularly carbon dioxide (CO2) from fossil fuel combustion. Anthropogenic emissions of non-CO2 greenhouse gases, such as methane, nitrous oxide and ozone-depleting substances (largely from sources other than fossil fuels), also contribute significantly to warming. Some non-CO2 greenhouse gases have much shorter lifetimes than CO2, so reducing their emissions offers an additional opportunity to lessen future climate change.

In this paper we describe a strategy for sustained release of nitrogen into the soil. Specifically, ureamodified hydroxyapatite nanoparticles were encapsulated under pressure into cavities of the soft wood of Gliricidia sepium.

A field experiment was conducted at the research farm of Indian Agricultural Research Institute, New Delhi during 3 wet and dry seasons of 2003-06 in rice-wheat cropping system. In this experiment different treatments comprising organic amendments such as blue green algae, vermicompost and farm yard manure applied alone or in combination were tested in organic crop production.

There is a need to break yield barriers through multidimensional approch to achieve food security on a sustainable basis for the people of this country. Cooperatives can play an important role in this direction due to their proximity to farmers. The Indian Farmers' Fertilizer Cooperative Limited (IFFCO), since over the last four decades, is providing services to farmers and cooperatives through various programmes, besides ensuring fertilizers availability.

During the late 1950s and early 1960s food deficits India has been requiring importation of 3 to 4 million tons of grain per year. However because of bad monsoons in 1965 and 1966, imports exploded unpwardly to 10 million tons, and India was in dire straits. It was during this period that, after three years of testing on experiment stations, the so-called high yielding Mexican wheat varieties, which had proven very interesting under experimental conditions, where considered as a possible way to break the worsening food deficit.
